Vittoria Cross Evo XN Tire - Tubular - Road Bike Shop

Knobs work great in loose material, but tend to offer higher resistance on hard, dry terrain. The Vittoria Cross EVO XN Tire offers the best of both worlds. A diamond-pattern tread on the top of the tire reduces rolling resistance, while side knobs bite into corners like a pit bull. The 320 TPI casing provides an extra-supple ride while the PRB puncture-resistant latex innertube ensures air stays where it's supposed to be--in your tires.
